Absolutely would buy again
Color: Orange
I love this, my pup loves this.
Strong, sturdy. Shakes all over the place.
Pup loves to chew on it, I think the vibration comforts her gums from teething.
Perfect size
You must take the outer skin off and pop open the white power button to charge it.
Total fun!

Rubber blue cover won't come off.
Color: Orange
If you want to keep the blue cover on that your dog chews off every other ball that is similar, get this one. Most dogs will not chew it off. It stretches when the chew on it so it can't be chewed or stretched off the ball. I've got a blind dog and she will kick it around for an hour at a time. It keeps her active and having fun.

Nice, but...
Color: Orange
It's a good idea & keeps my 1yr old Staffy/Pit occupied, BUT... The rubber around the ball is either too easy to chew through or my pup is just an aggressive chewer. Either way, it's a plus that it does come with an additional rubber, but it would be nice to also be able to buy additional ones vs having to buy the whole toy again & again! Oh, & if you think about letting them play with it without the rubber please be on the lookout for the rubber covering where you would charge it because my pup managed to locate & destroy that cover piece as well haha!

Entertains my husky!
After some research, I decided on this interactive toy for my young husky. I chose it over others because I liked that it was wrapped in a silicone cover so it wouldn't be as hard on her teeth, or my floors. It also seems to have helped with durability. She's never had this sort of automated toy before to engage with and it surprised her at first, but then she really got into it: pawing and nosing and sometimes howling at it. I was worried it would drive her and/or me crazy, but so far so good. She will play with it for a good 10 minutes at a time and it seems to provide some good mental stimulation since it rolls and spins unpredictably. It is easy to charge and was ready to use right out of the box. It has proved durable in the first week surviving my crazy pup and multiple trips down the stairs. I am also happy to report that it has worked pretty well on the carpet/rug areas of the home. It should work pretty well unless you have a very thick shag carpet. We'll see how long it lasts, but highly recommend so far.
